LiteSpeed SAPI is designed to be the fastest server API for inter-process communication between LiteSpeed Web Server and third party web application, protocol overhead has been reduced to minimum. Comparing to FastCGI protocol, LiteSpeed SAPI has about 25% speed advantage over FastCGI for simple "Hello World" application.

Nope. it is manual work as indicated in the previous post: you need to compile PHP with --enable-fastcgi--enable-discard-path --disable-path-info-check and create fastcgi handler and link to fcgi external app using the compiled PHP.

As you said - with-litespeed part of the erased, but when I compile via LSAP automatically re-added and deleted part of fastcgi.

What's why I said it is a manual thing. You can not use compile PHP from admin console which will add '--with-litespeed' option automatically. You have to manually compile from command line with needed options.

However, the expression wiki page so superficial and not a bad place but I'm choked up and I could not come up. No documents wiki did not help.

So your customers to torture, rather than compile time option with fastcgi module admin panel, you add or easyapache LSAP fastcgi collection made ​​from active even if you would be so nice on litespeed in the same way.

Litespeed is a performance-oriented working program to improve its performance must be available in each module, fastcgi support, but not positive to take all this trouble to set up. I hope that makes litespeed developers working on this issue later versions.
